Professional Applications & Engineering Value
This M12 hex head screw delivers critical performance in heavy-duty industrial applications where fastener failure is not an option. The Class 8.8 steel construction provides the necessary 110,000 psi tensile strength to withstand extreme mechanical loads in construction, machinery assembly, and structural frameworks. The zinc plated finish actively combats corrosion in humid or outdoor environments, significantly extending service life. With its partially threaded design and coarse metric thread (1.75mm pitch), this fastener offers superior resistance to vibration loosening while allowing precise adjustment in bolted joints. The external hex drive ensures compatibility with standard tools, streamlining installation in confined spaces common in industrial settings.
Specification Summary & Compliance
This M12 hex head screw features precise Class 6h thread fit according to ISO 4014 specifications (equivalent to DIN 931), ensuring dimensional accuracy and interchangeability. The 170mm length with 36mm minimum thread length provides optimal engagement for various material thicknesses. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, making it suitable for regulated industries and international projects requiring certified components.
